The Soldier in Afghanistan wasn't operating under orders: it wasn't a planned event; it was, in effect, an accident...an apology makes sense there.

Fast and Furious was planned, was executed to plan and, with the exception of their getting caught in the act, did exactly what they wanted it to: put American guns at Mexican crime scenes as a propaganda tool in support of their anti-gun agenda.

What's to apologize for?

The only thing they're sorry about is getting caught. As far as I'm concerned, an apology devoid of actual remorse is worse than no apology at all.
